An arrangement of a two-phase superconducting cable as a power supply cable in two-phase power distribution networks for electric railways include two phase conductors which are arranged coaxially with respect to one another and are separated from one another by an inner dielectric. A cryostat, with the superconducting cable arranged therein, has two tubes which run co-axially and at a distance from one another with vacuum insulation between them, where in addition to the superconducting cable, the cryostat surrounds a free space for a coolant to be passed through, and where an outer dielectric is fitted over the outer phase conductor of the superconducting cable.
